Hey Guys, Here's what I made to mount my Wheels and Brakes on my 1-1/4" Axles

I took two pieces of chromemoly... and made the pieces separate...

First piece of Chromemoly was 1-3/8" X .058 , it was used to bolt in the Axle and with a washer... push on theWheel Bearing , to keep the wheel in place....

The next piece of chromemoly was 1-1/2" X .058.... This also bolted to the axle thru the same hole as the other tube.This piece has a washer welded on it...and there's holes in the washer to mount the brake calipers.

Gotta Fly...

Sometimes you just have to take the leap and build your wings on the way down... Gotta Fly...

How did you decide on these brakes, wheels and tires? Also can you list what they are and your sources? I am impressed with your contributions to this website.
I am thinking about ordering a set of plans for the Buttercup as this project looks great. Keep up the great posting you hav been doing.

Hi Dragger,
Actually, a friend of mine (Kent) found the wheels... I was having a hard time finding a 6.00 X 6 wheel
to fit my 1-1/4" axle.... I thought I was going to have to get 5.00 X 5
As far as picking out the tire.... I wanted a good tire... This is a 4 ply , 120mph Goodyear
My Wheels and Disc brakes are Matco... only $432 for both sides.... I also bought the Matco Vertical mount Brake cylinder.

I'm glad you like the Building Log... I'm trying to make that extra effort to help others if they are building the same plane.
I wish "I" could see what others are doing on their Buttercups... But you only get a glimpse here and there...

Gotta Fly...

PS Ready to set the plane up and do a final check on the Lift Struts before welding them....

This was the FIRST set-up to measure how long to make the Lift Struts

Ok... The pieces were sandblasted and painted with 2 part epoxy primer.Assembling the brakes.I ordered my fittings and tubing through Matco , same place I bought the brakes years ago.The fittings match the tubing ...which match the brakes. Matco said I could use ATF, Automatic Transmission Fluid instead of MIL-H-5606 for my brake fluid.NO AUTO BRAKE FLUID...

Hopefully , I won't need to use brakes much...But those peSky PAVED airports...better be ready.Gotta Fly....PS...The second flight , Brakes were tested. (My first plane)viewtopic.php?f=180&t=3054#p3456

..I bought Brake line and fittings through Matco Brakes.I figured it matched their system..Yes , I bought 1/4 tube and fittings - But I ended up putting 1/8" tubing and fittings....

Here's why...

Trying to figure out just how the tube was going to be routed... I KINKED a spot....I thought I would need smaller tubing for tighter bends...( The tubing is fairly stiff ).But after "Sleeving the entire length of the small tubing with the 1/4 inch...It kind of told me 1/4" would have worked if I used the heat gun the first time...Oh well...Slower flow through a tighter hole gives it a longer "Throw" , better feeland it has a protective sleeve throughout flexing areas on the landing gear.

Something I changed... was the direction coming out of the vertical master cylinders.I WAS going to have 90 degree fittings pointed upward and hoops by the firewall...Instead... The shortest side for my "Torsion" roll seems to give it plenty of length to use (especially in the tubing sleeve)So I used straight fittings at the base.... Clean look and operation , nothing to snag after the lower panel is in place ( With batting ).Gotta Fly...

..These are some pictures filling the system with ATF...Just pump the oil can at the bleeder valve, til oil comes out of the vent at the other end.Since the plastic lines are clear , it was easy to see oil was moving..After I finished with both sides , I put the oil back into the container..I was surprised how 'Little" the system used...

I like the 1/8" lines... But I need to make something to protect and strengthen the area around the calipers...(working on it ).Gotta Fly.....

I put ANOTHER tube around the brake line , it also adds UV protection.I formed a piece of .032 aluminum to do a couple things... One ,protect the small exposed brake line at the fitting.(Deflector shield)Two...By tying into the curved bulk of brake line...the small line is protected/supported from shock too.If nothing else... This will at least protect it during building..Gotta Fly.....

.Finishing this Brake system means protecting Plastic lines that are aprox 3 inches away from the exhaust pipes.I knew I'd be coming to this...Just hadn't found the material (that wasn't 37 bucks a square foot).I thought about some material we had left over after installing the wood burning furnace in the new house...Tested it I was able to shape it easy with a saw blade or rough sanding block...even a rat tail..Gotta Fly.....

.Sealing the deal....A quick tape job with Aluminum duct stuff,helps seal the area between the panelsThis sheds the heat better..Checking the Fit of the outside panel too...(it still needs chaffing tape strip).The only other thing I did was put a piece of Dacron fabric over the hole at the brake cylinders.It closes the area more to keep debris out.I held it in place with polybrush.Now the brakes can be worked on from inside the cabin,,, The heat shield can be left inplace..This should wrap up this stage...I put someone in the cockpit to test the brakes as I pushed the fuselage back and forth.They work good for shop test,,, No leaks,,,Now let's see if we pass the heat test...Remember, I use a "Torsion" type of twist on my brake lines.I'll be inspecting it after the first cooling cycle .Gotta Fly.....
